CURRENT PUBLICATIONS (Ranked by Impact Factor of the Journal)

LABORATORY RESEARCH

Hierarchical Organization and Early Hematopoietic Specification of the Developing HSC Lineage in the AGM Region
In this study, investigators developed a new co-aggregation culture system, which supports maturation of a novel population of CD45-negative (VE-cad+CD45CD41+) pre-hematopoietic stem cells (HSCs) into definitive HSCs. [J Exp Med]

Stromal Cell-Derived Factor-1 (SDF-1) and Hematopoietic Cell Homing in an Adult Zebrafish Model of Hematopoietic Cell Transplant
Researchers sought to characterize sdf-1 expression and function in the adult zebrafish in the context of hematopoietic cell transplantation. [Blood]

Regulation of TMPRSS6 by BMP6 and Iron in Human Cells and Mice
In this study, scientists investigated whether bone morphogenetic protein 6 (BMP6) and iron also regulate TMPRSS6 expression. [Blood]

Guanine Nucleotide Exchange Factor Vav1 Regulates Perivascular Homing and Bone Marrow Retention of Hematopoietic Stem and Progenitor Cells
Researchers investigated the role of the hematopoietic-specific guanine nucleotide exchange factor Vav1 in hematopoietic stem and progenitor cells localization and engraftment. [Proc Natl Acad Sci U S A]

Importance of c-kit Mutation Detection Method Sensitivity in Prognostic Analyses of t(8;21)(q22;q22) Acute Myeloid Leukemia
In this study, investigators developed a highly sensitive mutation detection method known as mutation-biased PCR and investigated the relationship between c-kit mutations and prognosis. [Leukemia]

Differentiation of an Embryonic Stem Cell to Hemogenic Endothelium by Defined Factors: Essential Role of Bone Morphogenetic Protein 4
Scientists have developed a defined, serum-free and low cell-density differentiation program to generate endothelial and hematopoietic cells within 6 days from murine embryonic stem cells. [Development]

CLINICAL RESEARCH

Phase I Study of Epigenetic Priming with Decitabine Prior to Standard Induction Chemotherapy for Patients with AML
Researchers conducted an open label Phase I study exploring the feasibility, safety and biologic activity of epigenetic priming with decitabine prior to standard induction chemotherapy in patients with less-than-favorable risk AML. [Blood]

High Success of Hematopoietic Cell Transplantation Regardless of Donor Source in Children with Very High-Risk Leukemia
Investigators evaluated 190 children with very-high-risk leukemia, who underwent allogeneic hematopoietic cell transplantation in two sequential treatment eras, to determine whether those treated with contemporary protocols had a high risk of relapse or toxic death, and whether non-HLA-identical transplantations yielded poor outcomes. [Blood]

Missense Mutations in PML-RARA Critical for the Lack of Responsiveness to Arsenic Trioxide Treatment
Scientists report that two out of 15 patients with refractory/relapsed acute promyelocytic leukemia treated with arsenic trioxide (As2O3 ) were clinically As2O3 resistant. [Blood]
